簡介

The ZT485H series devices are 5V differential data line transceivers for RS485/RS422 communication that consist of one driver and one receiver with high level of ESD protection. They are designed for balanced transmission lines interface that meet ANSI standard TIA/EIA-485-A and ISO 8482:1987(E) specifications.

The ZT485H series devices spans out with half or full duplex, data rate guaranteed at 250K bit per second or 10Mbps, and allow one-eighth of an unit load that fan out 256 devices sharing a common bus. The I/Os are enhanced-electrostatic discharge (ESD) protected, exceeding ±15kV Human Body Model (HBM).

規格:

● Meets or exceeds the requirements of ANSI Standard TIA/EIA-485-A and ISO 8482:1987(E) specifications for V cc at +5V ±10%
● Low quiescent current – 0.5mA typ., 1mA max
● Low shutdown current (where applicable) - 1μA typical, 10μA max
● Guaranteed standard data rate 250Kbps or 10Mbps
● True Fail-Safe (Open, Short, Bus Idle) Receiver
● -7V to +12V common-mode input voltage range
● Half-Duplex mode configuration
● Allows up to 1/8 unit load (256 devices) on the same common bus
● Controlled driver output slew rate and receiver input filtering
● Active-high driver enable and active-low receiver Enable
● ESD protection on bus terminals
-- ±15kV Human Body Model (HBM)
● Alternative replacement for MAX308x, MAX1308x, SN75HVD308x, SN65HVD308x
● Standard fanout driving 1 unit load (32 devices) on the ZT485E Series
